Double message nightbot

Hello, my boyfriend use a nightbot for a YouTube Chanel but we have a problems. Nightbot will send two messages in a row. We have nothing to touch in the settings. When we request a nightbot command to not send the duplicate message but when it will send a message all by itself the message will be sent un duplicate and we do not understand why. I would like to have your help thank you


Thank you ! :slight_smile:
